Abstract

The invention relates to an automatic welding device and method for a nuclear power shielding main pump Canopy sealing ring, the automatic welding device comprises an annular guide rail, a movable seat plate, a welding device, a welding wire supply device, a walking driving mechanism and a control system, the annular guide rail is located below the Canopy sealing ring and is coaxial with the Canopy sealing ring, the movable seat plate is installed on the annular guide rail, and the movable seat plate is installed on the annular guide rail. The walking driving mechanism drives the movable seat plate to move along the annular guide rail, and the welding device and the welding wire supply device are installed on the movable seat plate. The welding device comprises a welding gun, a radial feeding mechanism for driving the welding gun to move in the radial direction of the annular guide rail, an angle adjusting mechanism for adjusting the elevation angle of the welding gun and a linear feeding mechanism for driving the welding gun to linearly move in the elevation angle direction of the welding gun. The welding wire supply device supplies welding wires to the welding gun. The control system controls actions of the walking driving mechanism, the radial feeding mechanism, the angle adjusting mechanism, the linear feeding mechanism and the welding wire supply device.

Description

technical field [0001] The invention relates to the field of inspection and maintenance of a shielded main pump for nuclear power, in particular to an automatic welding device and method for a Canopy sealing ring of a shielded main pump for nuclear power. Background technique [0002] Different from the shaft-sealed pump used in the second-generation and second-generation plus units, the third-generation AP1000 / CAP1400 series uses a single-stage, fully-sealed electric canned pump, which is the first use of canned pumps in the field of civil nuclear power. However, some abnormalities occurred during the actual manufacture, test and operation of the shielded main pump. In order to ensure the safe and reliable operation of the power plant, it is necessary to reserve the maintenance technology and devices of the shielded main pump in advance. The canned main pump adopts upright layout, see attached figure 1 And attached figure 2 As shown, the pump casing 1 is welded together ...
